London, Mar 1 (ANI): Tottering Hotspur ace Jermain Defoe has been dumped by his model girlfriend Chantelle Houghton because 'he's difficult to trust'.

Just a week ago Defoe, recovering from a broken toe, and Houghton were seen kissing on a romantic Dubai break.

However, soon after their return she gave him the elbow in an emotional phone call after fretting about his close relationships with female friends.

"He's a difficult guy to trust. She was always worrying what he was up to," News of the World quoted a pal, as saying.

Defoe has a history of cheating on girlfriends.

Apart from Houghton, he has dated ex-fiancée Charlotte Mears, Danielle Lloyd, David Beckham's little sister Joanne, glamour girl Sarah Giggle and ex-Big Bruv star Aisleyne Horgan-Wallace.

"Chantelle has never really been sure about Jermain. He has a string of girl 'friends' and is always on the phone. Most genuinely are his friends. But Chantelle just wants a quiet life with a man she can trust," the pal said.

Defoe tried to reassure Houghton that he would never cheat on her but the former Celebrity Big Brother champ has decided that it's over. (ANI)
